Scirocco CR170 "Project Racek0r"

[deano_123]

Spoiler looks awesome

Dd you see an improvement with the induction kit over the standard airbox?

[xjay1337]

Hopefully this is the kind of picture you wanted.

The back of the end plate is unlaquered, the spoiler itself is.

Regarding the airbox, no real improvement, spool felt a little stronger and it sounds awesome, that was the main reason lol.

Not sure on the michelin man now though...thinking of making taking off the large one on the rear.


Anyway, went to Santa Pod yesterday, had a good day.

2016-10-09_07-18-29 by Fat Bear Photography, on Flickr


Set a new PB, 13.6 @ 102.

I'm sure I could get to a 13.4 but I didn't want to break the car and I was happy to finally get into the mid 13s. Had a bit of luck with launching

Is your car manual or DSG?
mine is manual and I struggle to get under 14 seconds, and im running Revo stage 3 (K04) :/

Jay's is Manual.

Saw you at the pod! was going to come say Hi then had car issues... sorted herself out though!

I have the white rocco with the martini stripes!

Nice to see this car in the flesh yesterday and out on track, a few pics of it in action

Interesting reading the thread about driving standards, looking at the photos not great especially given the number of red flagged sessions

I think an afternoon session was the order of the day when the PHers had left

Funny the amount of people who have GT4s and cannot drive, more GT4s there than Golf Rs lol

[xjay1337]

Nice to see you mate and thanks!

I agree, I have it on video, the white GT4 literally went underneath me. He wasn't going flat out then again neither was I at the time (cooling oil down ) but had I been on a normal racing line it'd have been a very expensive accident.
Hopefully the event at Goodwood, if we are early enough to get track time, will be better.
I think the last Novice session of the day at about 3 people on it when we went back upstairs at 12:30!


I bought a couple of the pics and edited them slightly.

Car behaved itself well.
PS4's were brilliant on the front, stuck well but did feel a bit roly poly.
AD08R were good on the back, back end was dead planted. I think with 245/40 AD08R on the front it will really help.
Currently we are 235/40 F and 245/40 R.

When I ran 245/40 Direzza 03g it was so planted, but they are too expensive for daily use so while I only have 1 set of tyres I think the AD08Rs are a great compromise.

I've moaned about it elsewhere but oil temps are driving me mental.
I am booked in early November with Alex for oil cooler.

Once that's in I should be fine and able to keep on it a lot more.

Also my EGT protection was kicking in a lot, repeated long hard pulls get a bit much for it (understandable really).

i have specified when we port the head we fit oversized valves we are going up 0.8/0.9mm i believe.
Not sure what difference it will make and it's double the price as the valves are around 60EUR each but balls out and all that.

Saw you at the pod! was going to come say Hi then had car issues... sorted herself out though!

I remember seeing you on the strip

Shame you had problems but glad they fixed themselves lol

Oil cooler update.

Due to track related oil temperature problems I wanted a solution. I had an idea and spoke with Alex @ AKS and we decided to try some stuff.

Darkside Developments sell a kit with a Mocal thermostatic plate but the oil cooler provided was a cheap Chinese one, so that was sent back and Alex sourced a Mocal 13 row cooler and kept the Thermostatic plate.

20161110_104249 by Fat Bear Photography, on Flickr

I won't bore everyone with the fitting details but it wasn't exactly "bolt on".

We had to retain OEM oil cooler (OEM is a heat exchanger oil is circulated with coolant) however we had to modify the OEM oil cooler and remove the water feed.

20161110_131937 by Fat Bear Photography, on Flickr

Alex welding the brackets to give the right level of support.

20161110_151626 by Fat Bear Photography, on Flickr

Final fitted position.

20161110_185731 by Fat Bear Photography, on Flickr

We started at 10am and I left the workshop around 8pm. We weren't working on it flat out all day though, but it was a bit fiddly.

We did also fit H&R 28/24 front and rear roll bars. This has really stiffened it up in the corners. Lovely.

Oil temps are much better now. Cruising they get to around 80 and stay there due to thermostatic plate. Even with several hard and long acceleration pulls it barely reached 90 so that's much better. Very happy.

Very nice! Im still yet to fit my oil cooler, i havnt got the time recently
I have however got some grille mesh to fit infront of where the cooler will go to help avoid stones damaging it.

I'm hoping the location will be fine

The cooler itself is quite tough.
Fitting wasnt easy.

Met up with Bobby on Saturday at Surrey Rolling Road
Had a good afternoon chatting to people.

Due to some of the figures coming out of Europe (claiming 270bhp + on stock cp4 pump) we decided to run a test on my car.

We ran a new map, with a dummy EGT sensor (so no EGT protection)
requested lambda 0.9 (another 5-10% more fuel than before)
(normal tune lambda is 1.1-1.2)

20161112_121707 by Fat Bear Photography, on Flickr

Even with the extra fuel we were just getting extra smoke. Logs show lambda didn't get below 1.08.

You can see the graph before and after here. The pink (better curves) are the new v25 map and the blue ones were the old v24 map.

20161112_122514 by Fat Bear Photography, on Flickr

You can see while we have dumped loads more fuel in, we are now up to over 430 lb ft of torque however power is exactly the same as before, albeit it holds at the top end now (due to EGT protection effectively not working).

Flat power curve is all well and good but further proves no more airflow available.
We are slowly ruling out any mechanical restrictions to downpipe or intake however this further points to prove that airflow through CR170 head is poor.

We thought the OEM lambda probe was faulty or defective as we could not believe the logs so we ran an independant Lambda probe

IMG-20161112-WA0008 by Fat Bear Photography, on Flickr

Turns out the oem lambda was within range and not telling us lies. We are 100% out of air.



On this particular tune due to excess fuel we were seeing a peak of 2.7bar despite request 2.4

After testing we put v24 tune back on as this tune is not safe for daily use.

Driving to the shops. Pedal went to the floot.

I falsely diagnosed it as a duff slave cylinder. As my clutch is a heavy 6 paddle I imagined it was on it's way out anyway.
Infact , and luckily for my bank account, it wasn't anything so dramatic.
A clip which holds ones of the clutch lines in decided to disintegrate. Causing fluid leak and lack of hydraulic pressure.

I could have drove home clutchlessly but not ideal given my journey had lots of traffic lights etc.

Gave the car it's yearly wash and decontamination.

Just a gentle polish, combination of Scholl S20 Black and Megs 205 on a mediumy pad (Green Hexlogic if you're interested).

Coated with Gtechniq Crystal Serum light which was a breeze to be honest.

Thanks to Elite Car Care for the use of the unit :-)



I have a trackday on Friday at Bedford SEN. See how we stand with the oil cooler and suspension tweaks. (the H&R Rollbars and also fitted an UltraRacing underbody brace.

After that I am collecting a Blue Needle cluster. (mine has Red needles. Blue came on some R-Line models)
And also getting a braided clutch line done at AKS cos it's 5 minutes away, which completely removes the risk of having the OEM line and connections fail.
Annoyingly when we did the oil cooler we were going to do one but ran out of time.


I have sourced some additional parts as well with the help of Bobby, to help with power. My cylinder head is back with us now and the turbo is ready.

I have headbolts, just need a head rebuild kit with all the gaskets etc and some pipework and then the tear down will begin.

[xjay1337]

Did my first trackday of the year.

" onclick="window.open(this.href);return false;
(Footage from my first session at my first time at Bedford, I got a lot better but didn't take footage, I will explain).

I wanted to test out my oil cooler. It worked. I could go for about 6 or 7 flat out laps which is about 15 minutes, which is about as long as I do in any one sitting anyway.

Unfortunately, the car had other ideas.

20170120_144416 by Fat Bear Photography, on Flickr

The car decided to overheat, luckily caught it before it was too severe, and dump it's coolant onto the track / pits.
Despite this, there was no obvious leak. There was a shit ton of water around the reservoir, but it was also all over the engine bay, so no obvious point of egress.
I topped it up, bled it, seemed ok for the next session.
Then my third session, it did it again. So I stopped.

I went to AKS Tuning after, we fitted a braided clutch line.

20170120_163016 by Fat Bear Photography, on Flickr

Didn't really do much, slightly more feel which is good, but the main point is it eliminates the failure parts of the OEM clutch pipe.

We tried to find the water leak, but Alex nor I could see any obvious point of egress. Very annoying.

20170120_162300 by Fat Bear Photography, on Flickr

After further investigation, and an 80 mile drive today, it seems fine.
I suspect a couple of things may have happened.

1) Cylinder head lift (typical on big turbo TDI's).
Oem bolts are 10.9 tensile strength, at high boost and high heat situations you lift the head off the block which allows exhaust gasses into the cooling circuit , pressurising it.

2) A weak/failing O-ring on the coolant temperature sensor.
This seems to have some amounts of coolant on the pipe past it. We think this is the only obvious point of failure as there are no splits or leaks in the system . The o-ring / CTS will be replaced when we re-build the head.
I did go to see Bobby, my tuner, today as he needed to test a known-working Lambda sensor on another car he was tuning, while I was there, we pressure tested the cooling system and there was no leaks. The pressure tester was not 100% but we got to about 17psi and nothing was coming out with engine off or running.

I've parked that issue for now and just avoid extended high speed driving.

I also fitted a new dash cluster. As I had wanted blue needles for a long time and finally got around to getting them done.

Here is my OEM cluster.

20170120_055218 by Fat Bear Photography, on Flickr

and here's the replacement, it's from a Golf Mk6 GTD, but the needles were swapped and the SMD's on the dash cluster themselves were replaced to give the correct OEM blue type needles.

So not all bad news.

Nice as always!, quick Q,

as i just spotted it in your clocks pic, with the Kenwood upgrade that I can see there Trey nice, can you locate the mic into the headliner where its supposed to be? I expect you could adapt the cabling off the original factory one?
